Abstract
According to the present invention, there are provided a coloring composition comprising the compound represented by the general formula (1) described in the specification and at least one compound selected from the group consisting of the compound represented by the general formula (D) and the compound represented by the general formula (E), an ink for inkjet recording using the coloring composition, an ink jet recording method using the ink for inkjet recording, and an ink cartridge for inkjet printer filled with the ink for inkjet recording.
Description
Technical Field
The present invention relates to a coloring composition, an ink for inkjet recording, an inkjet recording method, and an ink cartridge for inkjet printer.
Background
As an ink jet recording method, a method of printing by causing ink droplets to fly and adhere to a recording medium such as paper is well known. This printing method enables high-resolution, high-quality images to be printed easily and at high speed with an inexpensive apparatus, and has been developed in recent years as an image forming method that can replace photographs, particularly in color printing.
For example, patent documents 1 and 2 describe an ink for inkjet recording containing a xanthene compound.

Disclosure of Invention
Technical problem to be solved by the invention
However, further improvement in performance is demanded for the field of dyes.
The present invention aims to provide a coloring composition which can form an image having excellent hue, chroma and tinting strength (print density), excellent light resistance, ozone resistance and moisture resistance, and excellent discharge stability in an ink jet printer, an ink for ink jet recording using the coloring composition, an ink jet recording method using the ink for ink jet recording, and an ink cartridge for ink jet printer filled with the ink for ink jet recording.
Means for solving the technical problem
The present inventors have conducted intensive studies and found that the above problems can be solved by the following means. In the present invention, by combining the compound represented by the general formula (1) and at least one compound selected from the group consisting of the compound represented by the general formula (D) and the compound represented by the general formula (E), it is possible to reduce (contribute to improvement in the discharge stability of the ink) the dye concentration contained in the coloring composition (ink) and to achieve both high coloring power (print density) and image fastness (light fastness, ozone fastness, and moisture fastness). The reasons for preference are as follows: by combining good hue and chroma and different pigment mother nuclei having high tinting strength, tinting strength and image fastness can be satisfied at a higher level than in the case of using each alone.
The detailed reason is not clear, but is estimated as follows: when the xanthene-based dye represented by the general formula (1) and at least one anthrapyridone dye selected from the group consisting of the compound represented by the general formula (D) and the compound represented by the general formula (E) are mixed (for example, in an ink for ink jet recording or an ink jet printed matter produced by an ink jet recording method: on an ink jet paper for exclusive use), the physical and chemical interactions are small, and the desired performance can be achieved without causing significant disadvantages such as reduction in light resistance and reduction in ejection stability of the ink.

< printing density >
By the combination of the ink jet printer and the recording paper, a full-surface coated image (a printed image at an applied voltage of 100%) was recorded using each ink for ink jet recording.
The print density of the entire surface coating image obtained was measured using a reflection densitometer (trade name X-Rite310TR, manufactured by X-Rite inc.), and the case where the print density was 2.0 or more was evaluated as a, the case where the print density was 1.8 or more and less than 2.0 was evaluated as B, the case where the print density was 1.7 or more and less than 1.8 was evaluated as C, and the case where the print density was less than 1.7 was evaluated as D in four stages.
< light resistance >
After the image density Ci immediately after recording was measured, the image was irradiated with 28 days xenon light (10 million lux) using a weatherometer (map c.165), the image density Cf1 was measured again, and the residual dye ratio was calculated from the image densities before and after xenon light irradiation, and evaluated. The image density was measured using a reflection densitometer (trade name X-Rite310TR, manufactured by X-Rite Inc.). The residual dye ratio was measured using an image portion having an initial image density of 1.0 ± 0.2.
The residual dye ratio was determined by the following formula, and the light resistance was evaluated based on the following criteria.
Residual dye ratio (%) (Cf1/Ci) × 100

The residual dye ratio was measured using an image portion having an initial image density of 1.0 ± 0.2. The ozone gas concentration in the tank was set using an APPLICS CORP ozone gas monitor (model: OZG-EM-01).
The residual dye ratio was determined by the following formula, and the ozone resistance was evaluated by the following criteria.
Residual dye ratio (%) (Cf2/Ci) × 100
A: when the residual rate of the pigment is 85% or more and less than 90%
B: when the residual rate of the pigment is 80% or more and less than 85%
C: when the residual rate of pigment is less than 80%
< moisture resistance >
Regarding bleeding of an image under high humidity conditions, a 1mm × 1mm square of magenta was arranged so that a 0.5mm white background gap was formed between the squares, and a 3cm × 3cm printed pattern was prepared, and this image sample was stored at 45 ℃ under a relative humidity of 80% for 7 days, and then, the bleeding of the magenta dye in the white background gap was observed.
Specifically, OD values of a printed matter before exposure to the above conditions (45 ℃ C., relative humidity 80% of the printed matter) and after storage for 7 days under the above conditions were measured using a reflection densitometer "Spectrilino" (product name: manufactured by Gretag Co.), and the increase in magenta concentration against a white background immediately after printing and after storage for 7 days under the above conditions was measured in a green filter in state A, where A is a case where the concentration is less than 0.02, B is a case where the concentration is 0.02 to less than 0.05, C is a case where the concentration is 0.05 to less than 0.10, and D is a case where the concentration is 0.10 or more.
< spitting stability >
First, immediately after each ink for inkjet recording was prepared, the discharge of ink from all the nozzles of the inkjet printer was confirmed by the combination of the inkjet printer and the recording paper. Then, the sheet was output to 100 sheets of recording paper, and evaluation was performed according to the following criteria, and as a result, the evaluation result was "a" in all examples and comparative examples. In addition, a4 paper was used for the size of the recording paper.
Next, after each ink for inkjet recording was kept at 40 ℃ and a relative humidity of 80% for 2 weeks, the inkjet printer and the recording paper (size of recording paper a4) were used in the same combination as described above, again using each ink for inkjet recording, and discharge of ink from all the nozzles of the inkjet printer was confirmed. Then, the sheet was output to 100 sheets of recording paper, and the discharge stability was evaluated based on the following criteria.
